Abstract: The invention concerns an assembly including an unbonded flexible pipe and an associated end-fitting having a through opening with a centerline and a front and a rear end. The unbonded flexible pipe has an innermost sealing sheath defining a bore with a centerline and a carcass arranged inside the innermost sealing sheath. The innermost sealing sheath and the carcass extend into the through opening via the front end of the end-fitting wherein the innermost sealing sheath is fixed in an annular sealing to the end-fitting: The carcass extends beyond the annular sealing. The unbonded flexible pipe further has an optical fiber in the bore wherein the optical fiber is arranged in a groove of the carcass in at least a sealing length section where the optical fiber passes the annular sealing.
